Idle the engine briefly before stopping (about 2 minutes), then slide the ignition switch to the “O” (OFF) position. See Figure 20.

Engine Idle Adjustment

The engine must return to idle speed whenever the throttle lever is released. Idle speed is adjustable, and must be set low enough to permit the engine clutch to disengage the cutting attachment when the throttle is released.

Idle Speed Adjustment

WARNING!

The cutting attachment must NEVER rotate at engine idle! If the idle speed cannot be adjusted by the proceedure described here, have the unit inspected at an authorized Shindaiwa dealer.

1.Place the unit on the ground, then start the engine and allow it to idle for 2-3 minutes until warm.

. If the attachment rotates when the engine is at idle, reduce the idle speed by turning the idle adjustment screw counter-clockwise. See Figure 21.

3.If a tachometer is available, the engine idle speed should be final adjusted to 3,000 (±250) min-1(rpm).

NOTE:

Carburetor fuel mixture adjustments are preset at factory on units with emission control systems and cannot be serviced in the field.

Checking Unit Condition

NEVER operate the unit with the cutting attachment shield or other protective devices (harness, ignition switch, blade retention clip, etc.) removed!

Use only authorized Shindaiwa parts and accessories with your Shindaiwa trimmer or brushcutter. Do not make modifica- tions to the unit without the written approval of Shindaiwa, Inc.

WARNING!

A cutting attachment shield or other protective device is no guarantee of protection against thrown objects. YOU MUST ALWAYS GUARD AGAINST FLYING DEBRIS!

ALWAYS make sure the cutting attach- ment is properly installed and firmly tightened before operation.

NEVER use a cracked or warped cutting attachment: replace it with a serviceable one.

ALWAYS make sure the cutting attach- ment fits properly into the appropriate cutter holder. If a properly installed attachment vibrates, replace the attach- ment with a new one and re-check.

ALWAYS stop the engine immediately and check for damage if you strike a foreign object or if the unit becomes tangled. Do not operate with broken or damaged equipment.

NEVER allow the engine to operate at high RPM’s without a load. Doing so could damage the engine.

NEVER operate a unit with worn or dam- aged fasteners or attachment holders.

NEVER cut with dull blades. Doing so will increase the risk of blade thrust and may also damage your equipment.
